Except that Morihei Ueshiba specifically said that it was some of those things.Hence the problem.
Of course, one could say that modern Aikido is different from what Morihei Ueshiba was doing, and they might have a point, but I think that most people would be loathe to admit that.
People could also say that modern AIkido is the best possible product of Ueshiba's work in martial arts and that chasing after the imagination-magnified legends of his skills is, at best, a somewhat fruity/eccentric enterprise that we are all a little embarassed to be a part of, and they'd definitely have a point. Particularly in light of the war criminal stuff and other signs that he was not that great of a person and a little bit crazy.
(I'll cop to that though).
